Supplementary data set for "Three-Dimensional Time Domain Simulation of Tsunami-Generated Electromagnetic Fields: Application to the 2011 Tohoku Earthquake Tsunami"
Four data files contain processed tsunami magnetic variations at ESA, B14, NWP, and CBI. Please read Section 4.3 in the main article for the detail of the processing. The contents in each file are composed of ten columns; time [min since 05:46 UTC on March 11, 2011] (one column), high-pass filtered XYZ at the target site (three columns), synthesized XYZ at the target site based on eq. (14) (three columns), and cleaned XYZ at the target site, i.e. data left after subtraction of synthesized data from high-pass filtered data (three columns). For a seafloor site, B14, not the high-pass filtered but just raw time-series are contained in the second to forth columns because of the shortage of the original time series at B14. Readers can easily plot the four data files by using the script, plot_CTS.sh, where CTS stands for Cleaned Time Series. The four postscript files were generated by this script. -- For use of data at B14, please also refer Ichihara et al.
